In a boiling liquid that bubbles, a round-shaped creature is drifting through the area with the flow of liquid.

"It's good, everybody's doing well."

"So now it's time for the first closure, and the inner cells are ready to divide."

With Huogu's command, the opening of the front and back sections of the floating cylindrical creature began to slowly close, as if a multicellular creature was closing its mouth.

"Very good."

Hogu watched the whole process with full attention, and to be honest, it still felt a little nervous.

This is the first trial operation, and Hogu can't be 100% guaranteed that nothing will go wrong, and many things are sometimes so unexpected, just like the double-walled cell not long ago.

"Next, start putting enzymes into the cavity."

As the command is given, a large number of enzymes that can break down proteins are produced by the epidermal cells in the lumen and released into the fluid in the lumen.

The microorganisms trapped in this cavity, whether they are viruses, bacteria, or fungi, are all broken down by the enzymes that disperse them.

The first thing to be broken down is microorganisms such as viruses, their structure is too simple, the shell is a layer of protein, bacteria, fungi and finally a layer of cell wall.

However, the cell walls of bacteria and fungi can't last long, and they are facing a group-level monster, and a single microbial individual like them wants to compete with it, which is tantamount to a fool's dream.

After another period of time, the microorganisms in the inner cavity were completely decomposed by the enzymes, and only amino acids remained in this solution.

The inner wall of the cavity absorbs, processes, processes, and passes these amino acids to those inner cells, which in turn deliver these nutrients to the epidermal cells, which act as the main defense.

Huo Gu watched the whole process with a little relief, except for the first opening and closing of the mouth, which required it to give instructions, all the others were completed by the cells themselves, which was also a big progress.

After that, Hogu continued to 'eat' for the second and third times, and as far as the results were concerned, they were not much different from the first, which was able to perfectly kill those microorganisms and break them down into amino acids for absorption.

"Then the next step is the manufacturing of the vision system."

After making sure that his life would not be threatened for the time being, Hogu put the 'vision system' on the agenda.

Information is extremely important at all times.

Hogu now urgently needed to determine where he was so that he could devise a survival strategy.

If you want to have an eye, you need to have an organelle that can respond to light.

However, at the moment there is no such organelle in Hogu.

"Eyespot......"

"Since I don't have it here, I might as well snatch it from the other guys."

"Well, that's it, capture those microbes, parse their genes, and then attach the original genes."

With that in mind, Hogu set out to capture the microbes.

The cylindrical creature's 'mouth' slowly opens.

With displacement and liquid flow, microorganisms are inhaled into the inner cavity of the cylindrical organism without resistance.

When the two penetrating channels are completely closed, a large number of enzymes are released, as before, and a large number of microorganisms are killed by the enzymes.

However, compared to before, there is still a difference, after most of the viral microorganisms have been killed, the enzymes are just depleted.

Blunder?

No, it wasn't a mistake, it was all the way Hogu had planned.

If there are too many enzymes, there will only be amino acids left in the lumen, and if there are too few enzymes, it will not be able to completely kill those viruses, and it will repeat the crisis like the previous phage.

The key is the amount of enzymes, not too much, not too little, the first few times to open and close the mouth, not only to observe whether there are defects in the design of this multicellular organism, but also to know how long the virus can survive in this environment full of enzymes.

When the enzyme is depleted, the liquid in the lumen no longer has the function of breaking down proteins.

The protein structures that have a connection function are stretched out, and they stand in the liquid of the inner cavity, and the microorganisms that are trapped in the inner cavity and scurrying around are easily captured by these protein structures.

In this way, Hogu can directly observe the captured single-celled organisms from his perspective.

"Hmm... This is ......."

The outermost layer of a tadpole-like single-celled organism is a relatively thick and very loose cell wall, which only plays a role in mitigating collisions, and cannot defend against viruses such as bacteriophages, or aggressive bacteria and fungi.

Then there is the cell membrane, which is mediocre, and the composition and structure of the cell membrane are basically the same.

Finally, there is the little tail that keeps waging, also known as flagella, which is what surprises Hogu the most.

With this sample, he can then design an external organ that drives the movement of the entire cluster of single cells, which makes the safety factor much higher.

At least when you encounter danger, you don't need to worry about running away.

"Flagella aside, the key is to find single-celled organisms with organelles such as 'eyespots'."

Hogu's attention shifts to looking at another single-celled organism that has been captured by a protein construct.

This time it was a single-celled organism with a double membrane and no cell wall, and compared to the previous one-cell, this one-celled organism was much more fragile.

There are no flagella on the outside, but it does not disappoint Hogu, because inside this cell, there is an organelle that appears to be mitochondria.

Mitochondria can be said to be the engine of the microscopic biological world, combining nutrients and oxygen, or other combinations, to achieve the transformation of energy forms.

For example, light energy rotation energy, chemical energy to light energy, chemical energy to heat energy...... Wait a minute.

Even if this primitive suspected mitochondrial organelle does not meet Hogu's current needs, with this mitochondria as a template, Hogu can completely design a mitochondria that belongs exclusively to a single-cell cluster.

"This is really good, but let's put it first, finding the eyepoint organelles is the most important thing, and it is too dangerous to not be able to observe the surrounding situation."

The long protein structure swings in the inner cavity, like a fishing line thrown by a master angler on the surface of the water.

One after another, single-celled organisms have been fished out by this thin line, among them, there are various types of organelles, and there are all kinds of strange things, but the only thing is that there are no bacteria with 'eyespot' organelles.
